Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing trigger systems for weapons, such as Glock-style pistols and AR-15 rifles, can misfire or fire continuously due to trigger fluttering, posing safety risks and legal liabilities.

Innovation Solution

The development of trigger systems that reliably fire every time without skipping, featuring components sized and positioned to prevent misfires due to trigger fluttering, and incorporating a dual-adjustment capability for customizable trigger pull force and firing sear tightness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If standard trigger components are used, then the trigger system is simple and easy to manufacture, but the trigger may flutter causing misfires or continuous firing

Engineering Contradiction:

Improvetrigger firing reliabilityVSAvoidtrigger system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The trigger system is divided into separate functional components: a trigger bar that moves laterally to release the firing pin, a separate firing pin, and a spring mechanism. This segmentation allows each component to be optimized independently for reliability while maintaining overall system simplicity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The trigger bar is designed with lateral movement capability rather than simple linear motion. This dynamic design allows the trigger bar to clear the firing pin reliably even during trigger flutter, ensuring consistent firing without requiring overly complex stabilization mechanisms

Inventive Principle:

Principle #15Dynamics

2Reliability

If flimsy components are used to catch and pull back the firing pin, then the device complexity is reduced, but the reliability of firing is compromised

Engineering Contradiction:

Improvefiring pin control reliabilityVSAvoidfiring pin mechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The firing pin features a curved or rounded tip that interfaces with the trigger bar. This curvature allows for smoother engagement and disengagement, improving reliability of firing pin control without requiring complex mechanical structures

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

A spring mechanism serves as an intermediary element between the trigger bar and firing pin, providing controlled force to ensure reliable firing pin release while maintaining simple overall system design

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the trigger pull force is fixed, then the device complexity is minimized, but the adaptability to different applications is reduced

Engineering Contradiction:

Improvetrigger pull adjustmentVSAvoidadjustment mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The trigger system incorporates adjustable components that allow users to modify trigger pull force and sear engagement characteristics. This dynamic adjustability enables the same basic mechanism to serve multiple applications from competitive shooting to self-defense without requiring complex electronic or mechanical systems

Inventive Principle:

Principle #15Dynamics
